Qt World Mapper example
|
||||
|
||||
It will show a basic Qt Widget, displaying world countries
|
||||
|
||||
|
||||
To compile this program:
|
||||
|
||||
Install Qt (if not done before)
|
||||
Install Boost (if not done before)
|
||||
|
||||
Using MSVC:
|
||||
- edit the file qt.vsprops
|
||||
- set the UserMacro QT to point to your Qt distribution
|
||||
- edit the file boost.vsprops
|
||||
- set the UserMacro BOOST_ROOT to point to your Boost distribution
|
||||
- alternatively you can include Boost and/or Qt in your standard include path
|
||||
|
||||
Using Linux/gcc
